Well you can't without hacking
find the chao key with tails.
No. lawl no.
SA2 is for the Dreamcast, while SA2B is for the GameCube. SA2 has Big cameos in the level, SA2B does not.(SA2B only has cut scene cameos but so does SA2.) SA2B has more 2 player stages than SA2. SA2 allows you to put your chao in the VMU, SA2B allows you to put your chao in the Tiny Chao Garden. SA2B has Chao Karate. some chao world structure is different.(dark garden is TOTALLY different.) There are more.
Its a hack or a cheat that lets you.
Yes if you beat the last challenge race the tv will be your prize.
You must do all the races and win all karate levels
To get a Knuckles Chao in Sonic Adventure 2 Battle (SA2B) using Action Replay, you can use the following code: 041B49C0 00000001. This code modifies the Chao to have Knuckles' appearance. Make sure to enter it correctly, and then you can check your Chao in the Chao Garden to see the change.
The chao can wear it as a hat. In SA2B your chao will need to have been given a skeleton dog at some point to allow it to wear hats.
I belive the only way to get more than 8 chao in both games is to get the action replay.
In order to get a moon chao,you must get every egg in your Garden(not at the same time), hatch them (in SA2B or the Garden) and put each chao in the garden(not at the same time).It costs 20,000 rings.
No but you can do the opoosite you have to go in the tiny chao garden and hook a gcn to gba cable and play sab2 then go to the chao garden and go to the gameboy choose pick up and choose the rings.
yes there is i think
